the first issue i encountered on twitch was the the amount of passive followers in a stream. You see for example 10000 followers, but only 100 viewers. That does not make many sense at all and gives a wrong first impression of a actually channel. So my idea is to get the difference of a active follower and an inactivefollower. That would first show you, how active a community is and the actually size of a community. Also the streamer has more of an idea, how the channel actually grows or is stagnating and can make a choice of rather its worth taking the risk to be a full time streamer. Also you can delete/unfollow passive followers of a channel after a certain amount of time(for example a half year). That would be beneficial for the company twitch/amazon and the streamers, also it doesn't seem like that at first glance. Passive followers doesn't earn you money in any way(,unless they subbed, pretty unlikely, numbers of how many passive followers had subbed would be pretty interesting and must be taken into consideration here.) The streamers knows, if his channel holds a certain standard or is increasing it's community. Therefore minimizing the risk of getting a full-timestreamer for small streamers, dependant only on to few informations. Yes, you see your subs, but that doesn't necessarily mean, you channel will grow constantly or will even hold your community at a certain level. This means, even you have once reached a certain standard, it's another question to get to a level like strawberry or ludwig. If a small streamer does have this information how the channle is evolving, many decisions on how to go further with it, are easier for the streamer. The same problem is to get partner or affiliate. The first standars are too low in my opinion. THe problem there is like with the passive followers. You only need to reach a certain amount once. You don't have to get it consistent for at least 1 month. Also you can see in a channel, if its worth it to get them partner of affiliate, based on active followers. It makes more sense to me at least instead of hoping as a little streamer to get it and than earn nothing.
Another positive side is that some people prefer small communities and have a better picture of this stream/streamer.
